Abstract: FIELD: defense industry; production of tank and anti-tank weapons. 
     SUBSTANCE: the invention is dealt with the field of production of tank and anti- tank weapons and may be used in complexes of tank and anti-tank arms, and also in small-sized antiaircraft complexes. The purpose of the offered invention is an increase of accuracy of a rocket pointing to a target at deviations of frequency of rotation of a rocket on a roll relatively to nominal value and dispersion of dynamic characteristics of a steering drive due to correction of a phase of entrance signals of a steering drive. It is achieved due to the fact, that the device of formation of the control commands containing the following in series connected units: a receiver, a unit of electronic equipment, a gyroscopic coordinator with a roll angle sensor, the first steering drive with the first summation unit and the first potentiometer of the feedback, the second steering drive with the second summation unit and the second potentiometer of a feedback, is added with the first and second units of subtraction, the first inputs of which are correspondingly connected to the first and the second outputs of the electronic equipment unit; the first, second, third and fourth modulators. At that the signal inputs of the first and third modulators are connected to the output of the first unit of subtraction, and the signal inputs of the second and fourth modulators are connected to the output of the second unit of subtraction; the third summation unit and the third unit of subtraction and the first input of the third summation unit are connected to the output of the first modulator; the second input of the third summation unit is connected to the output of the second modulator; and the output of the third summation unit is connected to the input of the first steering drive; the first input of the third unit of subtraction is connected to the output of the third modulator; the second input of the third unit of subtraction is connected to the output of the fourth modulator; the output of the third unit of subtraction is connected to the input of the second steering drive; the fifth, sixth, seventh and eighth modulators;. At that the signal inputs of the fifth and sixth modulators are connected to the output of the feedback potentiometer of the first steering drive, and the signal inputs of the seventh and eighth modulators are connected to the output of the feedback potentiometer of the second steering drive; the basic inputs of the first, fourth, fifth and eighth modulators are connected to the first output of the sensor of gyroscopic coordinator; the basic inputs of the second, third, sixth and seventh modulators are connected to the second output of the sensor of gyroscopic coordinator; the fourth unit of subtraction and the fourth summation unit; at that the first inputs of the fourth unit of subtraction and the fourth summation unit are connected to the outputs accordingly of the fifth and sixth modulators; the second input of the fourth subtraction unit is connected to the output of the seventh modulator; the second input of the fourth summation unit is connected to the output of the eighth modulator; the first and second amplifiers. At that the input of the first amplifier is connected to an output of the fourth unit of subtraction and its output - to the second input of the first unit of subtraction; the input of the second amplifier is connected to the output of the fourth summation unit and its output - to the second input of the second unit of subtraction; a source of stabilized different-polar voltage, the first output of which is connected to the first input of the sensor of the gyroscopic coordinator and the second output of which is connected to the second input of the sensor of the gyroscopic coordinator. 
     EFFECT: the invention allows to increase accuracy of the rocket pointing to a target at deviations of frequency of rotation of a rocket on a roll relatively to nominal value and dispersion of dynamic characteristics of a steering drive.
